The Aspidiaceae is a large but often poorly defined family of ferns. The separation or otherwise of this family from others such as Dryopteridaceae has often been contentious, but Wang (1965) pointed out the raised costa of the leaves in Aspidiaceae as a significant distinction. Members typically have round sori that may be covered by a reniform indusium.
Characters (Wang 1965): Middle-sized, terrestrial ferns; rhizome erect or sub-erect, dictyostelic, scaly; leaves tufted, generally uniform, simple pinnate to tripinnatifid; veins free or anastomosing, forming areoles with or without free included veinlets; rachis and costa raised on the upper surface and generally covered with pale brown multicellular articulate hairs; sori round or in a few cases acrostichoid; indusia reniform, or in some genera absent; spores bilateral with perispore.
